The Notes shall have the series designation, denominations, issue price, maturities, interest rates, redemption provisions, if any, and other terms as set forth in the General Disclosure Package (as hereinafter defined).

SECTION 1. Representations and Warranties. (a) Representations and Warranties by the Company. The Company represents and warrants to and agrees with each Underwriter that:

(i) An “automatic shelf registration statement” as defined in Rule 405 (“Rule 405”) under the Securities Act of 1933, as amended (the “Securities Act”), on Form S-3 (File No. 333-223472) to be used in connection with the public offering and sale of debt securities, including the Notes, and other securities of the Company under the Securities Act and the rules and regulations promulgated thereunder (the “Rules and Regulations”) and the offering thereof from time to time in accordance with Rule 415 under the Securities Act, has been prepared and filed by the Company not earlier than three years prior to the date hereof, in conformity with the requirements of the Securities Act and the Rules and Regulations. The Company will file with the Securities and Exchange Commission (the “Commission”) a prospectus supplement specifically relating to the terms of the Notes pursuant to Rule 424(b) (“Rule 424(b)”) under the Securities Act. The Company qualifies for use of Form S-3 for the registration of the Notes and the Notes are registered under the Securities Act. “Registration Statement” as of any time means such registration statement in the form then filed with the Commission, including any amendment thereto, any document incorporated or deemed to be incorporated by reference therein and any information in a prospectus or prospectus supplement deemed or retroactively deemed to be a part thereof pursuant to Rule 430B (“Rule 430B”) or 430C (“Rule 430C”) under the Securities Act that has not been superseded or modified. “Registration Statement” without reference to a time means the Registration Statement as of the Applicable Time (as hereinafter defined), which time shall be considered the “Effective Date” of the Registration Statement relating to the Notes. For purposes of this definition, information contained in a form of prospectus or prospectus supplement that is deemed retroactively to be a part of the Registration Statement pursuant to Rule 430B shall be considered to be included in the Registration Statement as of the time specified in Rule 430B. At the time of filing the Registration Statement, at the time of the most recent amendment thereto for the purposes of complying with Section 10(a)(3) of the Securities Act (whether such amendment was by post-effective amendment, incorporated report filed pursuant to Section 13 or 15(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or form of prospectus),

2

at the time the Company or any person acting on its behalf (within the meaning, for this clause only, of Rule 163(c) of the Securities Act) made any offer relating to the Notes in reliance on the exemption of Rule 163 of the Securities Act, and as of the date hereof, the Company was and is a “well known seasoned issuer” as defined in Rule 405 of the Securities Act.

(ii) At the time the Registration Statement initially became effective, at the time that each amendment thereto for the purposes of complying with Section 10(a)(3) of the Securities Act (whether by post-effective amendment, incorporated report or form of prospectus) became effective and on the Effective Date relating to the Notes, the Registration Statement conformed and will conform in all material respects to the requirements of the Securities Act and the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”), as the case may be, and the Rules and Regulations and did not and will not include any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading. On the date hereof, on the date of any filing pursuant to Rule 424(b) and on the Closing Date (as hereinafter defined), the Registration Statement and the Prospectus (as defined in this paragraph (ii)) will conform in all material respects to the requirements of the Securities Act, the Trust Indenture Act and the Rules and Regulations, and neither of such documents will include any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading, except that the foregoing does not apply to statements in or omissions from any of such documents made in reliance upon and in conformity with information furnished in writing to the Company by any Underwriter through the Representatives, if any, specifically for use therein or to any statements in or omissions from the Statement of Eligibility on Form T-1 of the Trustee under the Indenture, it being understood and agreed that the only such information furnished by any Underwriter consists of the information described as such in Section 7(b) hereof, but nothing contained herein is intended as a waiver of compliance with the Securities Act or the Rules and Regulations. For purposes of this Underwriting Agreement, “Statutory Prospectus” as of any time means the preliminary prospectus supplement (which term includes the base prospectus) relating to the Notes that is included in the Registration Statement immediately prior to that time, including any document incorporated by reference therein and any basic prospectus or prospectus supplement deemed to be a part thereof pursuant to Rule 430B or 430C that has not been superseded or modified. For purposes of this definition, information contained in a form of prospectus (including a prospectus supplement) that is deemed retroactively to be a part of the Registration Statement pursuant to Rule 430B shall be considered to be included in the Statutory Prospectus only as of the actual time that form of prospectus (including a prospectus supplement) is filed with the Commission pursuant to Rule 424(b) and not retroactively. “Prospectus” means the final prospectus supplement (which term includes the base prospectus) that discloses the public offering price and other final terms of the Notes and otherwise satisfies Section 10(a) of the Securities Act.

The preceding sentence does not apply to statements in or omissions from any prospectus included in the Registration Statement or any Issuer Free Writing Prospectus in reliance upon and in conformity with information furnished in writing to the Company by any Underwriter through the Representatives specifically for use therein, it being understood and agreed that the only such information furnished by any Underwriter consists of the information described as such in Section 7(b) hereof. “Applicable Time” means 4:30 p.m. (Eastern Time) on the date hereof. “Issuer Free Writing Prospectus” means any “issuer free writing prospectus,” as defined in Rule 433 (“Rule 433”) under the Securities Act, relating to the Notes.

(vi) Each Issuer Free Writing Prospectus, as of its issue date and at all subsequent times through the completion of the public offering and sale of the Notes or until any earlier date that the Company notified or notifies the Representatives as described in the next sentence and in Section 3(j) hereof, did not, does not and will not include any information that conflicted, conflicts or will conflict with the information then contained in the Registration Statement, the General Disclosure Package and the Prospectus. The foregoing sentence does not apply to statements in or omissions from any Issuer Free Writing Prospectus in reliance upon and in conformity with information furnished in writing to the Company by any Underwriter through the Representatives specifically for use therein, it being understood and agreed that the only such information furnished by any Underwriter consists of the information described as such in Section 7(b) hereof.

11

(c) To furnish without charge to the Representatives as many copies of the Prospectus and any documents incorporated by reference therein at or after the date thereof and any amendments and supplements thereto as the Representatives may reasonably request. The terms “supplement” and “amendment” as used in this Underwriting Agreement shall include all documents filed by the Company with the Commission subsequent to the date of the Prospectus pursuant to the Exchange Act which are deemed to be incorporated by reference in the Prospectus.

(d) Before amending or supplementing the Registration Statement or any Statutory Prospectus or filing with the Commission any document pursuant to Section 13, 14 or 15(d) of the Exchange Act, during the period referred to in paragraph (e) below, to furnish to the Representatives a copy of each such proposed amendment, supplement or document for the Representatives’ review prior to filing and not to file any such proposed amendment, supplement or document to which the Representatives reasonably object.

(e) The Company will promptly notify the Underwriters, and confirm such notice in writing (which notice and confirmation may be satisfied by providing the Underwriters with any related periodic report filed under the Exchange Act), of (i) any filing made by the Company of information relating to the offering of the Notes with any securities exchange or any other regulatory body in the United States or any other jurisdiction, and (ii) any material changes in or affecting the business, properties, results of operations or financial condition of the Company and its subsidiaries, taken as a whole, which (x) make any statement in the Prospectus as then amended or supplemented materially false or misleading or (y) are not disclosed in the Prospectus as then amended or supplemented. If, at any time when a prospectus covering the Notes is (or but for the exemption in Rule 172 under the Securities Act would be) required by law to be delivered in connection with sales of the Notes by an Underwriter or dealer, any event shall occur or condition shall exist as a result of which it is necessary, in the opinion of counsel for the Underwriters or counsel for the Company, to amend the Registration Statement or to amend or supplement the Prospectus or modify the information incorporated by reference therein in order that the Prospectus will not include any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances existing at the time the Prospectus is (or but for the exemption in Rule 172 under the Securities Act would be) delivered to a purchaser, not misleading, or if it is necessary to amend or supplement the Prospectus or modify such information to comply with the Securities Act and the Rules and Regulations, forthwith to prepare and file with the Commission and to furnish (subject to the conditions in paragraph (c) above), at its own expense, to the Underwriters and to the dealers (whose names and addresses the Representatives will furnish to the Company) to which Notes may have been sold by the Underwriters, and to any other dealers upon request, such amendments or supplements to the Prospectus or modifications to the documents incorporated by reference therein, so that the statements in the Prospectus as so amended, supplemented or modified will not, in the light of the circumstances existing at the time such Prospectus is delivered to a purchaser, be misleading or so that the Prospectus will comply with the Securities Act and the Rules and Regulations. If, prior to the Closing Date, there occurs an event or development as a result of which the General

12

Disclosure Package would include an untrue statement of a material fact or would omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances when the General Disclosure Package is delivered to a purchaser, not misleading, the Company promptly will notify the Representatives so that any use of the General Disclosure Package may cease until it is amended or supplemented, and will promptly prepare an amendment or supplement that will correct such statement or omission.

(f) The Company will use commercially reasonable efforts, in cooperation with the Underwriters, to qualify the Notes for offering and sale under the applicable securities laws of such jurisdictions as the Underwriters may designate and will maintain such qualifications in effect as long as required for the sale of the Notes; provided, however, that the Company shall not be obligated to file any general consent to service of process or to qualify as a foreign corporation or as a dealer in securities in any jurisdiction in which it is not so qualified or to subject itself to taxation in respect of doing business in any jurisdiction in which it is not otherwise so subject. The Company will file such statements and reports as may be required by the laws of each jurisdiction in which the Notes have been qualified as above provided. The Company will promptly advise the Representatives of the receipt by the Company of any notification with respect to the suspension of the qualification of the Notes for sale in any such state or jurisdiction or the initiating or threatening of any proceedings for such purpose. The Company will also supply the Underwriters with such information as is necessary for the determination of the legality of the Notes for investment under the laws of such jurisdictions as the Underwriters may reasonably request.

(g) The Company shall take all reasonable action necessary to enable Standard & Poor’s Financial Services, LLC, a subsidiary of S&P Global Inc. (“S&P”), Moody’s Investors Service, Inc. (“Moody’s”) and Fitch Ratings Inc. (“Fitch”) to provide their respective credit ratings of the Notes.

(h) The Company will use the proceeds received by it from the sale of the Notes in the manner specified in the Prospectus under “Use of Proceeds”.

(i) During a period beginning on the date of this Underwriting Agreement and continuing to and including the Closing Date, the Company will not, without the prior written consent of the Representatives, directly or indirectly, issue, sell, offer or agree to sell, grant any option for the sale of, or otherwise dispose of, any other debt securities issued or guaranteed by the Company or any of its subsidiaries substantially similar to the Notes or securities of the Company or any of its subsidiaries that are convertible into, or exchangeable for, the Notes.

(j) If at any time following the issuance of an Issuer Free Writing Prospectus there occurs an event or development as a result of which such Issuer Free Writing Prospectus would conflict with the information then contained in the Registration Statement, would include an untrue statement of a material fact or would omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances prevailing at that time, not misleading, (A) the Company will promptly notify the Representatives and (B) the Company will promptly amend or supplement such Issuer Free Writing Prospectus to eliminate or correct such conflict, untrue statement or omission.

13

(k) The Company will make generally available to its security holders, as soon as it is practicable to do so, an earning statement of the Company (which need not be audited, unless required so to be under Section 11(a) of the Securities Act), covering a period of at least 12 months beginning within three months after the “effective date” (as defined in Rule 158 under the Securities Act) of the Registration Statement, which earning statement shall satisfy the requirements of Section 11(a) of the Securities Act.

SECTION 4. Free Writing Prospectuses. (a) Free Writing Prospectuses. The Company represents and agrees that, unless it obtains the prior written consent of the Representatives, and each Underwriter represents and agrees that, unless it obtains the prior written consent of the Company and the Representatives, it has not made and will not make any offer relating to the Notes that would constitute an Issuer Free Writing Prospectus, or that would otherwise constitute a “free writing prospectus,” as defined in Rule 405, required to be filed with the Commission. The Company represents that it has complied and will comply with the requirements of Rule 164 under the Securities Act and Rule 433 applicable to any Issuer Free Writing Prospectus, including timely Commission filing where required, legending and record keeping. The parties hereto agree that the only Issuer Free Writing Prospectuses issued on or prior to the Applicable Time and consented to by the Company and the Representatives are specified on Schedule II hereto (including the final term sheet prepared in accordance with Section 4(b) below).

(b) Final Term Sheet. The Company will prepare a final term sheet relating to the Notes, containing only information that describes the final terms of the Notes and otherwise in a form consented to by the Representatives, and will file such final term sheet within the period required by Rule 433(d)(5)(ii). Any such final term sheet is an Issuer Free Writing Prospectus for purposes of this Underwriting Agreement and is specified in Schedule II hereto.

SECTION 5. Payment of Expenses. (a) Expenses. The Company will pay all expenses incident to the performance of its obligations under this Underwriting Agreement, including (i) the preparation, printing and any filing of each Statutory Prospectus, the Prospectus, any electronic road show and each Issuer Free Writing Prospectus and of each amendment or supplement thereto, (ii) the preparation, reproduction and delivery to the Underwriters of this Underwriting Agreement and such other documents as may be required in connection with the offering, purchase, sale and delivery of the Notes, (iii) the preparation, issuance and delivery of the certificates for the Notes to the Underwriters, including any charges of DTC in connection therewith, (iv) the fees and disbursements of the Company’s counsel, accountants and other advisors (but not the fees and disbursements of counsel for the Underwriters), (v) the qualification of the Notes under securities laws in accordance with the provisions of Section 3(f) hereof, including filing fees and the reasonable fees and disbursements of counsel for the Underwriters in connection therewith and in connection with the preparation of the Blue Sky Survey, any supplement thereto and any legal investment survey (such fees and disbursements not to exceed $7,500), (vi) the fees and expenses of the Trustee, including the fees and disbursements of counsel for the Trustee in connection with the Indenture and the Notes and (vii) any fees payable in connection with the rating of the Notes in accordance with Section 3(g) hereof.

14

(b) Termination of Underwriting Agreement. If this Underwriting Agreement is terminated by the Underwriters in accordance with the provisions of Section 6, the Company shall reimburse the Underwriters for all of their reasonable out-of-pocket expenses, including fees and disbursements of counsel for the Underwriters which were reasonably incurred.

SECTION 6. Conditions of Underwriters’ Obligations. The obligations of the Underwriters hereunder are subject to the accuracy of the representations and warranties of the Company contained in Section 1(a) as of the Applicable Time, the time this Underwriting Agreement is executed and delivered by the parties hereto and the Closing Date, to the accuracy of the statements made in certificates of the Company executed by any officer of the Company or any officer of any of the Company’s subsidiaries delivered pursuant to the provisions hereof, to the performance by the Company of its covenants and other obligations hereunder, and to the following further conditions:

(b) No Material Adverse Change. Subsequent to the execution and delivery of this Underwriting Agreement and prior to the Closing Date, there shall not have been, since the date hereof or since the respective dates as of which information is given in the General Disclosure Package and the Prospectus (exclusive of any amendments or supplements thereto subsequent to the Applicable Time), any Material Adverse Effect, whether or not arising in the ordinary course of business.

(c) Officer’s Certificate. The Underwriters shall have received on the Closing Date a certificate, dated the Closing Date and signed by an executive officer of the Company, to the effect set forth in Sections 6(a) and (b) above and to the effect that the representations and warranties of the Company in Section 1(a) were true and correct in all material respects when made and are true and correct in all material respects with the same force and effect as though expressly made at and as of the Closing Date, and that the Company has complied in all material respects with all agreements and satisfied all conditions on its part to be performed or satisfied at or prior to the Closing Date. The officer signing and delivering such certificate may rely upon the best of his or her knowledge as to proceedings threatened.

Reffner, Senior Vice President and General Counsel of FirstEnergy Service Company, and Jones Day, counsel to the Company, each in form and substance reasonably satisfactory to counsel for the Underwriters, together with signed or reproduced copies of such letters for the other Underwriters, and to such further effects as counsel to the Underwriters may reasonably request. Each counsel may state that, insofar as her or its opinion involves factual matters, such counsel has relied, to the extent she or it deems proper, upon certificates of officers of the Company and its subsidiaries and certificates of public officials.

(e) Opinion of Counsel for Underwriters. At the Closing Date, the Underwriters shall have received the favorable opinion, dated as of the Closing Date, of Ballard Spahr LLP, counsel for the Underwriters, in form and substance satisfactory to the Underwriters. In giving such opinion such counsel may state that, insofar as such opinion involves factual matters, they have relied, to the extent they deem proper, upon certificates of officers of the Company and its subsidiaries and certificates of public officials.

(f) Comfort Letter. (i) On or prior to the date of this Underwriting Agreement, the Underwriters shall have received from PricewaterhouseCoopers LLP a comfort letter, dated the date hereof, in form and substance reasonably satisfactory to the Underwriters, containing statements and information of the type ordinarily included in accountants’ “comfort letters” to underwriters (of the type ordinarily issued in transactions covered by registration statements filed under the Securities Act) with respect to the financial statements and certain financial information contained in the Registration Statement and any Statutory Prospectus and the Prospectus or incorporated therein by reference, with a specified date not more than three business days prior to the date hereof.

(ii) At the Closing Date, the Underwriters shall have received from PricewaterhouseCoopers LLP a letter dated as of the Closing Date, confirming, as of a date not more than three business days prior to the Closing Date, the statements contained in the letter delivered pursuant to Section 6(f)(i) hereof.

16

(h) Clearance and Settlement. At the Closing Date, the Notes shall be eligible for clearance and settlement through the facilities of DTC.

(i) Additional Documents. At the Closing Date, counsel for the Underwriters shall have been furnished with such documents and opinions as they may reasonably require for the purpose of enabling them to pass upon the issuance and sale of the Notes as herein contemplated, or in order to evidence the accuracy of any of the representations or warranties, or the fulfillment of any of the conditions, herein contained.

(j) Termination of Underwriting Agreement. If any condition contemplated by this Section shall not have been fulfilled when and as required to be fulfilled, this Underwriting Agreement may be terminated by the Underwriters by notice to the Company at any time at or prior to the Closing Date, and such termination shall be without liability of any party to any other party except as provided in Section 5 and except that Sections 7, 8, 9, 16(a) and 16(b) shall survive any such termination and remain in full force and effect.

SECTION 7. Indemnification. (a) Indemnification of Underwriters. The Company agrees to indemnify and hold harmless each Underwriter, its affiliates, each of its directors and officers and each person, if any, who controls any Underwriter within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act from and against any and all losses, claims, damages and liabilities that arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement at any time, any Statutory Prospectus at any time, the Prospectus, the General Disclosure Package or any Issuer Free Writing Prospectus, or arise out of or are based upon any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and agrees to reimburse each Underwriter and each such controlling person, as incurred, for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage or liability, except insofar as such losses, claims, damages or liabilities that arise out of or are based upon any such untrue statement or omission or alleged untrue statement or omission are based upon information furnished in writing to the Company by any Underwriter expressly for use therein, it being understood and agreed that the only such information furnished by any Underwriter consists of the information described as such in Section 7(b) hereof, or are based upon statements or omissions from that part of the Registration Statement that constitutes the Statement of Eligibility on Form T-1 of the Trustee. This indemnity agreement will be in addition to any liability which the Company may otherwise have.

17

(b) Indemnification of Company, Directors and Officers. Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company, its directors, its officers who sign the Registration Statement and any person controlling the Company within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the foregoing indemnity and reimbursement obligation from the Company to each Underwriter, but only with respect to untrue statements or alleged untrue statements or omissions or alleged omissions made in the Registration Statement, any Statutory Prospectus, the Prospectus, the General Disclosure Package or any Issuer Free Writing Prospectus in reliance upon and in conformity with written information furnished to the Company by the Underwriters through the Representative expressly for use therein. The Company acknowledges that the statements set forth in the last paragraph of the cover page of the Prospectus regarding delivery of the Notes and, under the caption “Underwriting (Conflicts of Interest),” (i) the concession and reallowance figures appearing in the third paragraph, (ii) the seventh paragraph, and (iii) the third sentence in the eighth paragraph related to market making activities, in the Prospectus constitute the only information furnished in writing by or on behalf of the several Underwriters for use in the Registration Statement, any Statutory Prospectus, the Prospectus or any Issuer Free Writing Prospectus. This indemnity agreement will be in addition to any liability which the Underwriters may otherwise have.

(c) Actions Against Parties; Notification. In case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to either of the two preceding paragraphs, such person (the “indemnified party”) shall promptly notify the person against whom such indemnity may be sought (the “indemnifying party”) in writing and the indemnifying party, upon request of the indemnified party, shall retain counsel reasonably satisfactory to the indemnified party to represent the indemnified party and any others the indemnifying party may designate in such proceeding and shall pay the fees and disbursements of such counsel related to such proceeding. The omission so to notify the indemnifying party (i) will not relieve it from any liability under paragraph (a) or (b) above unless and to the extent such failure results in the loss by the indemnifying party of substantial rights and defenses and (ii) will not, in any event relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraph (a) or (b) above. In any such proceeding, any indemnified party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (A) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel, (B) the named parties to any such action (including any impleaded parties) include both the indemnified party and the indemnifying party, and the indemnified party shall have reasonably concluded upon advice of counsel that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party or (C) the indemnifying party fails to assume the defense of such proceeding or to employ counsel reasonably satisfactory to the indemnified party. It is understood that, except as provided in the preceding sentence, the indemnifying party shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the fees and expenses of more than one separate counsel for all such indemnified parties. Such counsel shall be designated in writing by the Representatives in the case of parties indemnified pursuant to the second preceding paragraph, and by the Company in the case of parties indemnified pursuant to the first preceding paragraph.

18

(d) Settlement. The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there has been a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment. An indemnifying party will not, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding and (ii) does not include any statement as to, or any admission of, fault, culpability or failure to act by or on behalf of any indemnified party.

SECTION 8. Contribution. In the event that the indemnity provided for in Section 7 is held by a court to be unavailable, in whole or in part, to hold harmless an indemnified party for any reason, the Company and the Underwriters, severally and not jointly, agree to contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in connection with investigating or defending the same) (collectively “Losses”) to which the Company and any of the Underwriters may be subject in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and by the Underwriters on the other hand from the offering of the Notes. If the allocation provided by the immediately preceding sentence is held by a court to be unavailable for any reason, the Company and the Underwriters, severally and not jointly, agree to contribute in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company on the one hand and of the Underwriters on the other hand in connection with the statements or omissions that resulted in such Losses, as well as any other relevant equitable considerations. Benefits received by the Company shall be deemed to be equal to the total net proceeds from the offering (before deducting expenses) received by the Company, and benefits received by the Underwriters shall be deemed to be equal to the discounts and commissions received by the Underwriters. Relative fault shall be determined by reference to, among other things, whether any untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information provided by the Company on the one hand or the Underwriters on the other hand, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. Notwithstanding the provisions of this Section 8, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Notes underwritten by it and distributed to the public were offered to the public exceeds the amounts of any damages which such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. The Company and the Underwriters agree that it would not be just and equitable if contribution were determined by pro rata allocation or any other method of allocation that

19

does not take account of the equitable considerations referred to above. Notwithstanding the provisions of this Section 8, no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

For purposes of this Section 8, each person, if any, who controls an Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act shall have the same rights to contribution as such Underwriter, and each director of the Company, each officer that signs the Registration Statement and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act shall have the same rights to contribution as the Company. The Underwriters’ respective obligations to contribute pursuant to this Section 8 are several in proportion to the principal amount of Notes set forth opposite their respective names in Schedule I hereto and not joint.

SECTION 9. Representations, Warranties and Agreements To Survive Delivery. All representations, warranties and indemnity and contribution agreements contained in this Underwriting Agreement or in certificates of the Company submitted pursuant hereto shall remain operative and in full force and effect, regardless of any termination of this Underwriting Agreement, any investigation made by or on behalf of the Underwriters or controlling person, or by or on behalf of the Company, and shall survive delivery of the Notes to the Underwriters.

SECTION 10. Termination of Underwriting Agreement. The Underwriters may terminate this Underwriting Agreement by notice given by the Representatives to the Company, if after the effectiveness of this Underwriting Agreement and prior to delivery of and payment for the Notes (i) trading generally shall have been suspended or materially limited on, or by, the New York Stock Exchange, (ii) trading of any securities of the Company shall have been suspended on any exchange or in any over the counter market, (iii) any moratorium on commercial banking activities shall have been declared by Federal or New York State authorities or any material disruption in commercial banking, securities settlement, payment or clearance services in the United States shall have occurred, or (iv) there shall have occurred any outbreak or escalation of hostilities, or any change in financial markets, any declaration of war by Congress, or any calamity or crisis that, in the judgment of the Representatives, is material and adverse and which, singly or together with any other event specified in this clause (iv), makes it, in the judgment of the Representatives, impracticable or inadvisable to proceed with the offer, sale or delivery of the Notes on the terms and in the manner contemplated in the General Disclosure Package and the Prospectus. Sections 7, 8, 9, 16(a) and 16(b) shall survive any termination under this Section 10 and remain in full force and effect.

SECTION 11. Default by One or More of the Underwriters. If one or more of the Underwriters shall fail at the Closing Date to purchase the Notes which it or they are obligated to purchase under this Underwriting Agreement (the “Defaulted Notes”), the Underwriters shall have the right, but not the obligation, within 36 hours thereafter, to make arrangements for one or more of the non-defaulting Underwriters, or any other Underwriters, to purchase all, but not less than all, of the Defaulted Notes in such amounts as may be agreed upon and upon the terms herein set forth; if, however, the Underwriters shall not have completed such arrangements within such 36-hour period, then:

20

(a) if the number of Defaulted Notes does not exceed 10% of the aggregate principal amount of the Notes, each of the non-defaulting Underwriters shall be obligated, severally and not jointly, to purchase the full amount thereof in the proportions that their respective obligations to purchase hereunder bear to the obligations of all non-defaulting Underwriters, or

(b) if the number of Defaulted Notes exceeds 10% of the aggregate principal amount of the Notes, this Underwriting Agreement shall terminate without liability on the part of any non-defaulting Underwriter.

No action taken pursuant to this Section 11 shall relieve any defaulting Underwriter from liability in respect of its default under this Underwriting Agreement.

In the event of any such default which does not result in a termination of this Underwriting Agreement, either the Underwriters or the Company shall have the right to postpone the Closing Date for a period not exceeding seven days in order to effect any required changes in the Prospectus or in any other documents or arrangements.

SECTION 12. Notices. All notices and other communications hereunder shall be in writing and shall be deemed to have been given if mailed or transmitted by any standard form of telecommunication.

SECTION 13. Parties. This Underwriting Agreement shall inure to the benefit of and be binding upon the Underwriters, the Company and their respective successors. Nothing expressed or mentioned in this Underwriting Agreement is intended or shall be construed to give any person, firm or corporation, other than the Underwriters, the Company and their respective successors and the controlling persons and officers and directors referred to in Sections 7 and 8 and their heirs and legal representatives, any legal or equitable right, remedy or claim under or in respect of this Underwriting Agreement or any provision herein contained. This Underwriting Agreement and all conditions and provisions hereof are intended to be for the sole and exclusive benefit of the Underwriters, the Company and their respective successors, and said controlling persons, officers and directors and their heirs and legal representatives, and for the benefit of no other person, firm or corporation. No purchaser of Notes from the Underwriters shall be deemed to be a successor by reason merely of such purchase.

21

SECTION 14. Absence of Fiduciary Relationship. The Company acknowledges and agrees that:

(a) the Underwriters have been retained solely to act as underwriters in connection with the sale of Notes and that no fiduciary, advisory or agency relationship between the Company and the Underwriters have been created in respect of any of the transactions contemplated by this Underwriting Agreement, irrespective of whether the Underwriters have advised or are advising the Company on other matters;

(b) the price of the Notes set forth in the final term sheet attached as Annex A to Schedule II hereto was established by the Company following discussions and arms-length negotiations with the Underwriters and the Company is capable of evaluating and understanding and understands and accepts the terms, risks and conditions of the transactions contemplated by this Underwriting Agreement;

(c) the Company has been advised that the Underwriters and their affiliates are engaged in a broad range of transactions which may involve interests that differ from those of the Company and that the Underwriters have no obligation to disclose such interests and transactions to the Company by virtue of any fiduciary, advisory or agency relationship; and

(d) the Company waives, to the fullest extent permitted by law, any claims it may have against the Underwriters for breach of fiduciary duty or alleged breach of fiduciary duty and agrees that the Underwriters shall have no liability (whether direct or indirect) to the Company in respect of such a fiduciary duty claim or to any person asserting a fiduciary duty claim on behalf of or in right of the Company, including stockholders, employees or creditors of the Company.

SECTION 15. Recognition of the U.S. Special Resolution Regimes.

(a) In the event that any Underwriter that is a Covered Entity (as defined below) becomes subject to a proceeding under a U.S. Special Resolution Regime (as defined below), the transfer from such Underwriter of this Agreement, and any interest and obligation in or under this Agreement, will be effective to the same extent as the transfer would be effective under the U.S. Special Resolution Regime if this Agreement, and any such interest and obligation, were governed by the laws of the United States or a state of the United States.

22

(b) In the event that any Underwriter that is a Covered Entity or a BHC Act Affiliate (as defined below) of such Underwriter becomes subject to a proceeding under a U.S. Special Resolution Regime, Default Rights (as defined below) under this Agreement that may be exercised against such Underwriter are permitted to be exercised to no greater extent than such Default Rights could be exercised under the U.S. Special Resolution Regime if this Agreement were governed by the laws of the United States or a state of the United States.

For purposes of this provision: (i) a “BHC Act Affiliate” has the meaning assigned to the term “affiliate” in, and shall be interpreted in accordance with, 12 U.S.C. § 1841(k); (ii) a “Covered Entity” means any of the following: (A) a “covered entity” as that term is defined in, and interpreted in accordance with, 12 C.F.R. § 252.82(b); (B) “covered bank” as that term is defined in, and interpreted in accordance with, 12 C.F.R. § 47.3(b); or (C) a “covered FSI” as that term is defined in, and interpreted in accordance with, 12 C.F.R. § 382.2(b); (iii) “Default Right” has the meaning assigned to that term in, and shall be interpreted in accordance with, 12 C.F.R. §§ 252.81, 47.2 or 382.1, as applicable; and (iv) “U.S. Special Resolution Regime” means each of (A) the Federal Deposit Insurance Act and the regulations promulgated thereunder and (B) Title II of the Dodd-Frank Wall Street Reform and Consumer Protection Act and the regulations promulgated thereunder.

SECTION 16. MISCELLANEOUS. (a) GOVERNING LAW AND TIME. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO THE PRINCIPLES OF CONFLICTS OF LAWS THEREOF. EXCEPT AS OTHERWISE SET FORTH HEREIN, SPECIFIED TIMES OF DAY REFER TO NEW YORK CITY TIME.
